PATHOLOGY

Detailed explanation-1: -The thyroid gland secretes the thyroxine hormone in the bloodstream. Thyroxine hormone acts as a regulator of the metabolic rate of the body. Its primary function is to stimulate the metabolism of carbohydrates, proteins, and fats in the cells to produce energy.

Detailed explanation-2: -Thyroxine is the main hormone secreted into the bloodstream by the thyroid gland. It plays vital roles in digestion, heart and muscle function, brain development and maintenance of bones.

Detailed explanation-3: -Metabolism: Thyroid hormones stimulate diverse metabolic activities most tissues, leading to an increase in basal metabolic rate. One consequence of this activity is to increase body heat production, which seems to result, at least in part, from increased oxygen consumption and rates of ATP hydrolysis.

Detailed explanation-4: -The thyroid gland produces thyroxine (referred to as T4), which is a relatively inactive prohormone, and the highly active hormone called triiodothyronine (referred to as T3). Collectively, thyroxine and triiodothyronine are referred to as the thyroid hormones.

Detailed explanation-5: -Thyroxine plays a crucial role in heart and digestive function, metabolism, brain development, bone health, and muscle control. It affects almost all of the body’s systems, which means proper thyroxine levels are vital for health.
